High Resolution (0.0005 cm1) Spectroscopy of Carbon Disulfide with Interleaved Mid-IR Frequency Combs

We measured the high-resolution absorption spectrum of the carbon disulfide (CS 2 ) v3v+1 band using a broadband dual-comb subharmonic OPO system. The 14.5-MHz effective resolution was achieved by interleaving eight comb spectra with 115-MHz intermodal spacing.
